Description

The present invention relates to a vehicle

  roadside of the type comprising a chassis

  essentially by a pair of spars connected in-

  be them by sleepers and a superstructure

  load fixed to the chassis. In many cases, a road vehicle such

  than a truck, trailer or semi-trailer intended

  born to special transport such as the transport of motor vehicles is not used for

  full time for the spot to which it is normal-

  ment intended and it would be desirable to use it for

transport of another kind.

  The object of the invention is to produce a vehicle

  cule whose load-bearing superstructure is inter-

  changeable with other special projected structures

  for other purposes, such as a platform

  me, a box, a plate-carrying superstructure, a boat-carrying superstructure, etc. According to the invention, this object is achieved by means of a road vehicle of the type mentioned above, characterized in that the load-carrying superstructure in turn includes a basic chassis

  separate from the vehicle chassis and made up of

  tiellement by a pair of side members connected together by crosspieces, by the fact that the side members of the vehicle chassis include side supports in console, at least towards the front part and towards the

  rear part of this chassis, by the fact that the chassis

  sis of the load-carrying superstructure comprises crosspieces located opposite the console supports and provided with support blocks on these supports, and by the fact that each console support and each support block are provided with reciprocal fixing means has quick release to make it easily removable and

  replaceable load carrier superstructure.

  The object of the invention will be better understood

  thanks to the detailed description which follows, referring

  to the appended drawings given as a non-ll.

  Figure 1 is a side elevation of a truck fitted with a removable superstructure in the form of a vehicle superstructure, Figures 2 and 3 are elevations

  similar to Figure i and on a larger scale, re-

  separately presenting the truck and the vehicle-carrying superstructure, and FIGS. 4 and 5 are fragmentary views of corresponding parts, which can be connected together, of the chassis of the vehicle and of

  the removable load-carrying structure which can be combined

ciée to this chassis.

  With reference to FIGS. 1 to 3, a truck or a motor car of land for the transport of motor vehicles comprises a chassis, designated as a whole by 10, the front part of the chassis carries a cab II the chassis 10 (see also the figures 4 and) comprises a pair of side members 12, connected between

  them, in particular by a front cross member 14 and a

pour back 16.

  Chassis 10 is associated with a superstructu-

  re load carrier which, in the example shown, is in the form of a vehicle carrier superstructure,

  type with two superimposed platforms.

  The superstructure, visible in its entirety in FIGS. 1 and 3, in turn comprises a base chassis 18, distinct from the chassis 10 of the vehicle. The chassis 18 also essentially consists of a pair of shaped spars 20, connected between them by crosspieces, including a front crosspiece 22 and

a rear cross member 24.

  The base frame 18 of the superstructure is equipped with tracks (not shown) for the support

  motor vehicle wheels (normally

  tures) to transport and therefore constitutes a lower transport platform.

  Starting from base frame 18, the super

  removable structure supports a higher platform

  re, also intended for the transport of vehicles and indicated by the reference 26 which also indicates the

stringers.

  The upper platform 26 is supported,

  starting from the base chassis or lower platform

  re 18, by means of a pair of uprights before 28 and

  a pair of rear uprights 30.

  The front part of the upper platform

  rieure 26 is movable vertically along the

  aunts 28 between the raised position of FIGS. 1 and 3 and a lowered position on the lower platform or

  base frame 18, and can also tilt back

  re The rear uprights 30 are articulated to the lanyards

  Rons of the upper chassis Internally, they are

  articulated to posterior appendages 20 has lanyards

  rons via sliders that can slide

  in guides 31 which form part of appendices 20 a.

  The rear uprights 30 are part of elevation means which also include a pair of oscillating stays 32 Each rear upright 30 is articulated, at an intermediate point of its length and

  around a horizontal transverse axis, at an extremi-

  tee of a respective stay 32 The two oscillating stays 32 are fitted, parallel to each other, so as to constitute a rigid fork, on a single shaft

  common transverse means of control of the oscil-

  lation of the fork are provided and include a pair of hydraulic cylinders 34, the upper ends of which are articulated to the struts 32 and the lower ends of which are articulated at the point of the top, directed downwards, of a lowered part 36,

  practically in V, spars 20 of the superstructure

  removable structure The lowered part 36 is located behind

re the rear wheels of the truck.

  The shaft of the fork, the teeth of which are formed by the props 32, is supported so as to be able to rotate by sockets or sleeves 38 fixed

  to the rear cross member 24 of the chassis 18 of the super

structure.

  Fixing and supporting the superstruc-

  vehicle carrier ture (or other carrier structure

  load) on the chassis 10 of the vehicle are advantageous

designed as follows.

  The front cross member 14 of the chassis 10 of the vehicle

  cule has a pair of supports on each side

  in console 40, better visible in FIG. 4 At the

  right of the console supports 40, the front crosspiece 22 of the chassis 18 of the superstructure has blocks

corresponding support 42.

  The support blocks 42 are preferably of the unified hollow type "ISO" with lower slot. The console supports 40 carry fixing means of the rotary key type 44, called "twist-lock", whose key 44 can be engage in block 42 at

through its lower slot.

  At the rear cross members 24 of the chassis 18 of the superstructure, the side members 12 of the chassis 10 of the vehicle carry a pair of supports

  console side 46 Each of these supports in

  sole 46 is fitted with fixing means of the "twist-

  lock "above, the key of which is indicated at 48 Correspondingly, to the crosspiece 24 of the chassis 18

  of the superstructure, are incorporated blocks of ap-

  then of the aforementioned "ISO" unified type, indicated by 50 The blocks 50 allow the rear part of the

  chassis 18 of the superstructure to chassis 10 of the vehicle

  cule, thanks to the rear fixing means of the "twist-lock" type. A load-bearing superstructure like that which is shown in particular in FIG. 3, while being distinct from the chassis 10 of the vehicle, is endowed with its own rigidity thanks to the presence of the side members 20 which can be in a box or formed of

  which are connected to each other by the cross-

  its correspondents The superstructure can therefore be removed from the transport vehicle without risk

  to undergo harmful deformations.

  During transport, the rigidity of the chassis

  of the vehicle contributes to the rigidity of the super

  structure In addition, the most stressed points of the superstructure, which are located at the front uprights 28 and rear uprights 30, are connected in a robust, although removable, manner to the chassis

  of the vehicle, by 'ttwist-lock 10 systems

  me, the rigid fork socket shaft made up

  killed by the struts 32 is precisely in the zone where the rear part of the superstructure is connected to the chassis 10 of the vehicle, that is to say on the cross-member 24 which is fixed in a robust manner to the supports

in console 46.
